Designed for secure installation on prepared flat roofs

Roof lanterns are designed to be installed onto a correctly prepared, weathered builder’s upstand. Follow the relevant installation guide and use a competent contractor.

✓
Prepared builder’s upstand Ensure the external upstand dimensions match the selected lantern configuration.
✓
Weathered and insulated base The upstand should be square, weathered and insulated before fitting.
✓
Follow the correct guide Use the official installation guide for the selected roof lantern configuration.
✓
Competent installation Use a competent contractor and check access, lifting and weather conditions before delivery.

Installation checklist

Confirm the selected size matches the external builder’s upstand.
Check the upstand is square, level, weathered and insulated.
Confirm the roof lantern layout and glass configuration before fitting.
Use the relevant official installation guide.
Plan safe access and lifting for the delivered glass and frame.

Key measurement details

Measurement basis Product sizes refer to the external builder’s upstand dimensions.
Roof opening The suitable upstand pitch is 0° to 5°, with a minimum upstand height of 150mm and minimum width of 85mm where suitable fixing is available.

Roof Lantern glass options explained

Choose the glass configuration that suits your project. The selector offers toughened-over-toughened and toughened-over-laminated options; the selected configuration determines the inner pane specification.

What is the difference between laminated glass and toughened glass?

Laminated glass has two layers bonded with a clear interlayer. If the glass cracks, the interlayer helps hold it together. Toughened glass is heat treated to make it stronger, but if it breaks, it breaks into small pieces and falls away.

What is toughened-over-laminated glass?

Toughened-over-laminated combines a toughened outer pane with a laminated inner pane. The laminated inner pane helps hold the glass together if damaged and is available as a selectable configuration. Toughened-over-toughened is also available where offered by the selector.

When should I consider blue solar-control glass?

Blue solar-control glass is useful where reduced glare and solar heat gain are required, particularly on south-facing roofs or large glazed spaces exposed to direct sunlight.

Roof Lantern
I’m picky about finishes - this passed the test. We went for 2000 x 1500 with Grey outside / White inside. Minor note: a one‑page quick-start guide in the box would be handy, but our installer was fine.

Thank you for your review. We’re delighted to hear you’re happy with the finish and colour combination of your 2000 x 1500 rooflight. We also appreciate the helpful feedback about a one-page quick-start guide and will take this on board. Thanks again for choosing Daylight Systems.
Roof Lantern
I bought a Brett Martin roof lantern to replace a frameless rooflight from another brand that I got not long ago, and it was nothing but hassle. The difference is night and day. The build quality is great, and the customer service was really helpful throughout.

For anyone thinking about buying a roof lantern, don’t make the same mistake I did. Buy from Daylight Systems as you’re buying directly from Brett Martin themselves. Couldn’t be happier.

Thanks for leaving this review - we’re really pleased you made the switch and that the difference has been so noticeable.

It’s great to hear the build quality and our support team both stood out, especially after a frustrating experience elsewhere. And you’re absolutely right: ordering from Daylight Systems means you’re buying direct from Brett Martin. Thanks again for the recommendation - we really appreciate it.
Glass Roof Lantern
Bought a Glass Roof Lantern (1500 x 1000) in the 4 Pane Contemporary style with white interior / grey exterior and clear TGH/TGH glazing. It’s made a huge difference to the space - the room feels noticeably brighter and the slim frame gives it a really clean, modern finish from both inside and out.

Build quality feels solid and well-made, and once fitted it looks properly “architectural” rather than bulky. The glazing looks great and the overall unit feels premium. Installation onto a prepared upstand was straightforward for our installer and it’s been completely weathertight.

Also worth mentioning: the pricing/discount on my order was excellent value for what you get. Really happy overall and I’d recommend it to anyone upgrading a kitchen extension or flat roof area.
